CULTIVATOR ATTACHMENT.

Specification of Letters Patent.

Patented Dec. 14, 1909.

Application filed July 28, 1909. Serial No. 509,970.

I To all whom it may concern:

Be it known that I, EDGAR L. Ross, a citi- Zen of the United States, residing at Hico, in the county of Hamilton and State of Texas, have invented certain new and useful Improvements in Cultivator Attachments, of which the following is a specifica tion.

This invention relates to an attachment for cultivators, and more particularly to an attachment whereby a four plow cultivator can be converted into a six, or more, plow cultivator, and also a harrow.

The object of the invention comprehends the production of a device of this character which will be extremely simple in construction and can be easily and readily applied to the usual four plow cultivator wlthout changing any of its parts.

The invention is illustrated in the acc0m-. panying drawings, in which Figure 1 is a top plan view showing the invention applied to a cultivator; Fig. 2 is a side elevation thereof, detached; Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2.

Referring specifically to the drawings, 1 indicates a frame comprisin a flat piece of metal bent to form longitudinal spaced bars 2, to which the several parts of my invention are attached. The free ends of the bars 2 are united by blocks 3, for a purpose to be hereinafter described.

Secured to the bars 2, by means of eye bolts 4 is a member 5 comprising a vertical stem 6 and an oflset portion- 7 extending at right angles to the stem and having its end bent downwardly, as indicated at 8. Passing around the lower ends of the stem 6 and the portion 7 are the eyes 4 of the bolts 4, and by extending the stems of said bolts 4 transversely between the bars 2 of the frame 1 and tightening the clamping nuts 9 against the adjacent edges of said bars 2, the member 5 is securely held in position on the frame 1.

Located adjacent opposite ends of the frame, and on the same side thereof, are adjustable cufi's 10 to which the plow feet 11 are secured, in a manner to be hereinafter described. Each of the ends 10 comprises rear plates 12 provided with a central opening 13'and diametrically opposite openings 14, arranged midway between said opening 13 and the periphery of the plate. These plates 12 are also provided with projections 15 arranged diametrically opposite and at right angles to the openings l tadapted to have their straight faces 16 engage opposite edges of the bars 2, to prevent the rear plates from turning. Placed adjacent the outer faces of the rear plates 12 are front plates 17 also provided with a central opening 18 which registers with the opening 13, and diametrically opposite slots 19 arranged concentric with the openings 14. Secured to the outer faces of the front plates 17 are projections 20 provided with vertical grooves 21.

The manner of assembling the parts above described is as follows: The plates 12 and 17 are connected by bolts 22 passing transversely through the openings 14 and slots 19, and held therein by nuts 23. The plates are then placed against the edges of the bars 2 and the stems 11 of the feet 11 placed in the vertical grooves 21, the eyes of the eye bolts 2 1 are then placed around the stems 11 and passed through the openings 13 and 18 and transversely between the bars 2 and securely held in place by tight-' ening the clam ing bolts 25 against the adjacent edges of said bars. It will thus be seen that by loosening the nuts 23 of the bolts 22, the front plates 17 may be turned on the rear plates 12 to the extent of the slots 19, and as the stems Il -of the plow feet 11 are securely connected to said front plates, the tilt of said plow feet can be adusted.

To regulate the depth to which the plows enter the ground, I 'provide the upper ends of theside bars of the feet with a series of transverse openings 26 which are adapted to register with an opening 27 formed in the stems 11}. It will be seen by reference to the drawings that the stems 11 are pivotally mounted between the side bars of the feet, as' at 28. A pin 29 passed through certain of the openings 26 and the opening '27 serves to hold the feet at the'desired adjustment.

By removing the cuffs 10 and plow feet 11 from the frame 1, and attaching a number of similar cuffs 30, similar to the cuffs 10, only smaller, and securing thereto the shanks of the harrow teeth 31,"by means of eye bolts 32 and clamping nuts 33, the cultivator-may be converted into a harrow. Mounted in an opening 3* formed in the hereinbefore mentioned block 3 is the shank as both frames are identical, a descrlption of both will not be necessary.

The manner of attaching the frames 1 to the cultivator beams is as follows: Remove the front plows from the cultivator beams and insert the upper ends of the stems 5 into the eyes of the bolts from which the plows were removed, and by roper ad'ustment of the cuffs and plow eet the p ows carried by the beams can be adjusted to corfeet and cuffs to the bars, and means respond to the rear on the beams.

I claim In an attachment for cultivator-s, a pair of frames comprising longitudinally spaced bars, adjustable cuffs having plow feet secured '-thereto, eye bolts for securin said %or attaching said bars to the forward end of the cultivator beams.

In testimon whereof I aflix my signature, in presence 0 two witnesses.
